    Choosing between a 45W and a 65W charger may seem straightforward, but the right option depends on the devices you use and how you charge them.\r\n            <br><br>\r\n            A 45W charger provides enough power for many smartphones, tablets, and selected lightweight laptops. A 65W charger offers additional power capacity, making it a more versatile option for compatible laptops and users who charge multiple devices.\r\n            <br><br>\r\n            However, higher wattage does not automatically mean faster charging. The actual charging speed depends on the device's supported input power, charging protocol, cable specifications, and other operating conditions.\r\n            <br><br>\r\n            So, which charger should you choose? Let's compare their power output, charging performance, compatibility, and practical applications.\r\n        <\/p>\r\n        <ul class=\"dc-hero-tags\">\r\n            <li>45W Charger<\/li>\r\n            <li>Chargeur 65W<\/li>\r\n            <li>USB PD<\/li>\r\n            <li>PPS<\/li>\r\n            <li>Chargement de l&#039;ordinateur portable<\/li>\r\n            <li>Adaptateurs secteur<\/li>\r\n        <\/ul>\r\n    <\/div>\r\n\r\n    <!-- ===== TABLE OF CONTENTS\uff08\u542b\u951a\u70b9\u94fe\u63a5\uff09 ===== -->\r\n    <div class=\"dc-article-toc\">\r\n        <div class=\"dc-toc-heading\">Table des mati\u00e8res<\/div>\r\n        <ul class=\"dc-toc-list\">\r\n            <li>\r\n                <a href=\"#section-1\">1.

A charger must support the device's required charging protocol and output profiles.\r\n    <\/p>\r\n\r\n    <h3 class=\"dc-subsection-title\" id=\"section-3-2\">3.2 What About Different Charging Protocols?<\/h3>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        USB Power Delivery is widely used across modern smartphones, tablets, and laptops, but some manufacturers also use proprietary fast-charging technologies.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        A charger that supports USB PD may not provide the maximum advertised charging speed for a device that requires a different protocol or a specific PPS profile.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        This does not necessarily prevent charging. It may simply result in a lower charging speed.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        When choosing a third-party charger, check:\r\n    <\/p>\r\n\r\n    <ul class=\"dc-reading-list\">\r\n        <li>USB PD compatibility.<\/li>\r\n        <li>PPS support when required by the device.<\/li>\r\n        <li>Supported voltage and current profiles.<\/li>\r\n        <li>Appropriate safety and regulatory compliance.<\/li>\r\n        <li>Cable compatibility and power rating.<\/li>\r\n    <\/ul>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        A higher-wattage charger is generally a flexible option, provided its specifications match the connected device.\r\n    <\/p>\r\n\r\n    <!-- ============================================================\r\n         4.

Which charger is better for laptops and phones?<\/h2>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        Choosing between a 45W and 65W charger depends on the devices you use most often.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        A 45W charger is suitable for many smartphones, tablets, and lightweight laptops. A 65W charger is a better fit for compatible laptops that require more power.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        If you regularly carry a laptop and a phone, a 65W multi-port charger may also reduce the number of adapters you need to carry.\r\n    <\/p>\r\n\r\n    <h3 class=\"dc-subsection-title\" id=\"section-4-1\">4.1 Which Charger Should You Pick?<\/h3>\r\n\r\n    <div class=\"dc-table-wrap\">\r\n        <table>\r\n            <thead>\r\n                <tr>\r\n                    <th>Type d&#039;appareil<\/th>\r\n                    <th>Recommended Option<\/th>\r\n                    <th>Reason<\/th>\r\n                <\/tr>\r\n            <\/thead>\r\n            <tbody>\r\n                <tr>\r\n                    <td><span class=\"dc-spec\">Smartphone Only<\/span><\/td>\r\n                    <td>45W or 65W<\/td>\r\n                    <td>Both can work; actual speed depends on phone support<\/td>\r\n                <\/tr>\r\n                <tr>\r\n                    <td><span class=\"dc-spec\">Tablet Only<\/span><\/td>\r\n                    <td>45W or 65W<\/td>\r\n                    <td>Choose according to the tablet's charging requirements<\/td>\r\n                <\/tr>\r\n                <tr>\r\n                    <td><span class=\"dc-spec\">Lightweight Laptop<\/span><\/td>\r\n                    <td>45W or 65W<\/td>\r\n                    <td>Check the manufacturer's recommended wattage<\/td>\r\n                <\/tr>\r\n                <tr>\r\n                    <td><span class=\"dc-spec\">Laptop Requiring 65W<\/span><\/td>\r\n                    <td>65W<\/td>\r\n                    <td>Better matches its power requirement<\/td>\r\n                <\/tr>\r\n                <tr>\r\n                    <td><span class=\"dc-spec\">Laptop + Phone<\/span><\/td>\r\n                    <td>65W multi-port charger<\/td>\r\n                    <td>More power capacity for compatible devices<\/td>\r\n                <\/tr>\r\n                <tr>\r\n                    <td><span class=\"dc-spec\">High-Power Gaming Laptop<\/span><\/td>\r\n                    <td>Manufacturer-recommended adapter<\/td>\r\n                    <td>65W may be insufficient<\/td>\r\n                <\/tr>\r\n            <\/tbody>\r\n        <\/table>\r\n    <\/div>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        One important point: not every laptop can be charged adequately with a 65W USB-C adapter. Some performance laptops require considerably more power, and certain gaming laptops use dedicated power adapters.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        For example, Apple recommends different adapter ratings for different MacBook models. Some MacBook Pro models require 96W or 140W adapters for their recommended charging configurations.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Always check the laptop manufacturer's charging specifications before purchasing an adapter.\r\n    <\/p>\r\n\r\n    <h3 class=\"dc-subsection-title\" id=\"section-4-2\">4.2 What About Charging Multiple Devices?<\/h3>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        A multi-port charger can be convenient if you want to charge a phone, tablet, and laptop using one adapter.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        However, the total rated wattage does not necessarily go to a single device when multiple ports are in use.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        For example, a 65W multi-port charger may distribute its output between two or more connected devices. The available power on each port depends on the charger's power-allocation design.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Before purchasing one, check:\r\n    <\/p>\r\n\r\n    <ul class=\"dc-reading-list\">\r\n        <li>Total maximum output.<\/li>\r\n        <li>Individual USB-C port output.<\/li>\r\n        <li>Power distribution when multiple ports are occupied.<\/li>\r\n        <li>Supported PD and PPS profiles.<\/li>\r\n        <li>Whether the charger can maintain sufficient laptop charging power while charging another device.<\/li>\r\n    <\/ul>\r\n\r\n    <!-- ============================================================\r\n         5.
